Roskilde in the context of "Lands of Denmark"

Roskilde Cathedral (Danish: Roskilde Domkirke), in the city of Roskilde on the island of Zealand (Sjælland) in eastern Denmark, is a cathedral of the Lutheran Church of Denmark.

The cathedral is one of the most important churches in Denmark, and the official royal burial church of the Danish monarchs. It is also a UNESCO World Heritage Site. This is due to two criteria: the architecture of the cathedral shows 800 years of European architectural styles, and it is one of the earliest examples in Scandinavia of a Gothic cathedral to be built in brick; it encouraged the spread of the Brick Gothic style throughout Northern Europe. Constructed during the 12th and 13th centuries, the cathedral incorporates both Gothic and Romanesque architectural features in its design. The cathedral has been the main burial site for Danish monarchs since the 15th century. As such, it has been significantly extended and altered over the centuries to accommodate a considerable number of burial chapels and the many added chapels show different architectural styles.

The Treaty of Roskilde was negotiated at Høje Taastrup Church and was concluded on 26 February (OS) or 8 March 1658 (NS) during the Second Northern War between Frederick III of Denmark–Norway and Karl X Gustav of Sweden in the Danish city of Roskilde. After a devastating defeat, Denmark–Norway was forced to give up a third of its territory to save the rest, the ceded lands comprising Blekinge, Bornholm, Bohuslän, Scania and Trøndelag, as well as Halland.

After the treaty entered into force, Swedish forces continued to campaign in the remainder of Denmark–Norway, but had to withdraw from the Danish isles and Trøndelag in the face of a Dano–Norwegian and Dutch alliance. The Treaty of Copenhagen restored Bornholm to Denmark and Trøndelag to Norway in 1660, while the other provinces transferred in Roskilde remained Swedish.

Region Zealand (Danish: Region Sjælland) is an administrative region of Denmark. It is one of the five classified NUTS-2 statistical regions of Denmark. It was established on 1 January 2007 as part of the 2007 Danish Municipal Reform, which abolished the traditional counties ("amter"). The region incorporates the southernmost parts of the country, and encompasses an area of 14,197 km (5,481 sq mi). Zealand will merge with the Capital Region of Denmark on 1 January 2027 to create the Region of Eastern Denmark.

The region shares the island of Sjælland (Zealand) with the neighbouring Capital Region of Copenhagen. The region also includes the islands of Lolland, Falster, and Møn. It incorporates the provinces of Østsjælland and Vest-og Sydsjælland, which consists of 17 municipalities. With a population of just over 0.85 million, it is the second least populated of the all the regions in Denmark. The largest city is Roskilde.
